Five years ago my husband and I visited Vienna and Hallstatt. Everyone else should too. Hallstatt is backed up to the Austrian Alps and to get to the village you take a boat. Our boat driver bore an uncanny resemblance to Cliff on Cheers.
But we didn't go when it was all summer-ish like in the above picture. The below picture is more like it.
We stayed at the inn below - Gasthof Simony. Our window balcony looked over the water and swans: it was pretty much perfect.
